plural of orbiter

(sciences) By means of or in relation to orbit / (physics, chemistry) By means of or in relation to an orbital or orbitals

(astronomy) Of, or related to an orbit or orbiting.

(astronomy) The surface (plane) that contains an orbit.

(chemistry, physics) an atomic or molecular orbital whose energy increases as its constituent atoms are brought closer together - thus generating a repulsive force that hinders bonding

The orbit of a satellite that is nearer the planet than it would be if it were in synchronous orbit

(physics, chemistry) The properties of an atomic orbital or molecular orbital that characterize its symmetry; especially those properties that are conserved in a chemical reaction.

(quantum mechanics, chemistry) A mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

(quantum mechanics, chemistry) The quantum mechanical behaviour of an electron in a molecule describing the probability of the electron's particular position and energy; approximated by a linear combination of atomic orbitals.

A satellite orbit where the orbital period is equal to, or multiples of, the Earth’s rotational period; i.e. making one, two, three, etc., orbits in a 24-hour period. Examples include geosynchronous (period equals Earth's rotation), semisynchronous (two orbits per day); and geostationary (geosynchronous orbit where satellite maintains a fixed position on the equator).
